Review on 🚰 Threaded Protector Dispenser: Reusable Drinking Solution for Hygienic Refreshment by Kevin Farmer

This product was initially great. It didn't even bother me that I had to return the first order I received because one of the spouts that came in two packages was torn. What worries me is that despite constant cleaning, the interior upholstery is turning gray-purple and mold has grown from the inside out. (Photo was taken after soaking it in hot water/soap and then vinegar.) I don't feel comfortable putting it back on the Culligan water jug in the office so it's thrown away. Shame.
